🔹 Definition
A Suspicious Activity Report (SAR) is an official document submitted by financial institutions or obligated entities to a regulatory authority when they detect a transaction or behavior that may involve money laundering, terrorist financing, fraud, or other financial crime. SARs are a key tool in financial intelligence gathering and are mandatory under AML laws in many jurisdictions.
The purpose of a SAR is to alert authorities to potentially illegal activity without tipping off the customer involved—a principle known as the non-tipping-off rule.
🔹 Frequently Asked Questions (FAQs)
Q1: What types of activities trigger a SAR?
- Unusual transaction patterns inconsistent with the customer’s profile
- Structuring (smurfing) to avoid reporting thresholds

- Customer refusal to provide KYC documents or providing obviously false information
- Use of unexplained third-party funds or complex ownership structures
Q2: Who is required to file a SAR?
- Banks, fintechs, and payment processors
- Corporate service providers (CSPs) and Registered Filing Agents (RFAs)
